Age of the machines - MIning Decisions

‘The challenge in gold mining is that the rock is even harder than PGM-bearing rock and rock stress is very high, given depths of more than 4 km,’ it states. ‘24/7 mechanised mining systems would allow the exploitation of lower-grade reefs as well as deep high-grade reefs and high-grade pillar recovery.’ One case study refers to Amplats’ testing of equipment for hard rock, mechanised ...

Quartz reef mining - Wikipedia

Quartz reef mining is a type of gold mining in "reefs" (veins) of quartz. Quartz is one of the most common minerals in the earth's crust, and most quartz veins do not carry gold, but those that have gold are avidly hunted by prospectors. In the shallow, oxidized zones of quartz reef deposits, the gold occurs in its metallic state, and is easily recovered with simple equipment. Quartz reef ...
